MIXING UTENS IL Filed Nov. '29, 1940 illy/rally ATTORNEY.

Patented Dec. 16, 1941 UNITED STATES I This invention relates to improvements in mixing utensils; and the invention has reference, more particularly', to aA novell utensili comprising a covered mixing vesself having a manipulata'ble mixing agitator and a novel auxiliary ingredient feeding means detachably related thereto;

In the operation of mixing together the constituents of which` some compositions arevv formed, it is frequently necessary, order to obtain a desiredproper blending thereof in the composition, that a given constituent orI ingredient be added and worked into` a` preliminary mixture of the other ingredients; An" example off a composition requiring such mixing method-is an edible dressing. known asm-ayonnaise, in the'prepar'ation of which the egg yolks, vinegar,lemon juice Vand other seasoning constituents are first mixed together, and then into such initial mixture is thereupon introduced olive or other edible oil, in such gradual mannerthat thorough emulsication of the oil is obtained with resultant proper blending thereof. Withth'einitial mixture, thereby to complete the: ultimate composition..

Having the above-in vfi'ewit isan. object of this invention to provide in combination with. a covered mixing vessel', having areciprocatory and preferably rota-tableV mixing agitator, a novel auxiliary ingredient` supply andv feeding means adapted to be'detachaloly` mounted on: the vessel cover' for operative communication through theA latter with the interior of said vessel;

Other objects of this invention, not at this time-morefparticularly enumerated, will beunderstood from the followingdetailed description rof the same.

A11 illustrative embodiment of this invention is shown in the-accompanyingdrawing,in which:`

Fig. 1 is a top end view' of the covered mixing vessel? with the. auxiliary ingredient supply and feeding' means operativelymountedupon the vessel cover andl in communication with the vessel interior; Fig. 2 is a longitudinal vertical sectional view thereof, taken online 2--2'in Fig.. l; Fig. 3 is a fragmentary 'side elevation with parts in section, and shovvingthe auxiliary ingredientsupplyy and feeding means detached from the vessel.

cover in the process of removing the same from the vessel; and Fig'is a-topend: View of the covered mixing Vessel with the'aluxiliary ingredientvs'upply and feeding4 means removed, and the cover port which serves the latter in closed condition.

Similar characters of reference are employed in the above described views, to indicate corresponding parts.

Referring to said drawing, the reference'- character III indicatesthemixing vessel having an open top end. Said vessel may be made ofr any suitable material, but is `.preferably madeof glass.

Cooperative with the open top end of said vessel,

so Vas to close the same, is a detachable cover member I I. `The top end portion of the vessel and the skirt of the cover member I'IV are pro-f vided' withcooperative means for -detacha'bly se-l curing the latter to the former. Such means may varyV as to'specific form; illustrative, however, of one. practical form thereof, as shown in the drawiings, are the .male screw-'threads I2 with which the top' end portion of the vessel is provided and: the cooperatingrk female screw-threads I3 With which the *skirtA of the cover member II: is provided.

The manipulatablemixing agitator with which the mixing vessel is provided comprises a perpen dicular shaft I4 of rectangular crossl section, intermediate the ends of. which is formed' av spiralI section I5. The cover memberv Il is provided, in a central location, with a bearing boss I6 having a bearing ropening II conformable to the c'ros'si sectional shapeof said shaft; The shaft I4 extends downwardly through said'V bearing opening Il into the interior of saidmixing vessel. Affixed upon the lower interior end of said shaft I4" is Va mixer or agitating device comprising a plurality of' radialV blades I8 suitably curved'andf pitched so as 'toagitat'e the material contained inthe mix.- ing vessel when moved therethrough ,Connectedk to the upperexterior end of saidA shaft I4, in swiveling relation thereto, is: a handle member I'9S by which the shaft I4 may be axially reciprocated through the bearingopening I1 ofthe covermember bearing boss I6.. When the` shaftv I4 is thus reciprocated its 4spiral section' I5 is causedto traverse saidy bearing bossopening I7 whereby'to The novel, auxiliary added ingredienti feeding;y

means.` which. isi providedY for detachable connection with the cover member Il of the mixing vessel, comprises a suitably shaped basin 20 having a suitably located tubular discharge spout 2l downwardly projecting from the bottom thereof.

Although the basin 20 may be variously formed as to shape, it is preferable that its shape be such as to provide an outwardly open indenting portion 22 extending to the center thereof, whereby, when mounting or dismounting the same from the cover member II, it may be moved laterally relative to and so as to straddle the exteriorly projecting portion of the shaft I4 of the mixer or agitating device. In order to admit the tubular discharge spout 2I of the basin 20 for communication with the interior of the mixing vessel II), the cover member II is provided with a suitably located opening or port 23 through which said spout 2| may extend when the basin 20 is operatively mounted on the mixing vessel cover member II. is means for closing the same when the basin is removed and the mixing vessel is in use forY mixing already contained ingredients of a composition under preparation. This means for closing the opening or port 23 is subject to more or less variation as to form, but illustrative of one practical form thereof as shown in the drawings, the same comprises a pivoted cover disc 24 rotatably pivoted to the cover member II by a pivoting rivet 25 or the like. Said cover disc 24 is provided with an opening 26, which, upon proper rotatable shift of said cover disc 24, may be brought into alignment and registration with the opening or port 23 (see Figs. 2 and 3), or may be shifted to move said opening 26 out of alignment with said opening or port 23 whereby the body of the cover disc closes said opening or port 23 (see Fig. 4). Upstanding from said cover disc 24 is a finger piece 21 by which it may be manipulated. Means are provided for releasably securing the basin against accidental shift or displacement from its operative applied relation to the cover member II when mounted thereon. Here again such securing means may be provided in various forms, but illustrative of one such form as shown in the drawing, the same comprises cooperative fastener elements with which the cover member I I and the bottom of the basin 20 is provided. Preferably such fastener elements comprise a resilient female coupler or upwardly open snap socket member 28 which is mounted, e. g. on the cover member I I, and a male coupler member 29 which is aixed to the bottom of the basin 20 to project downwardly therefrom. If the basin 20 is of the laterally indented or bifurcate form above described and shown in the drawing, two sets of said fastener elements respectively associated with the respective horns or arms of the basin may be provided.

When use of the basin is desired, the cover disc 24 is moved to position for exposing the opening or port 23 of the cover member I I, whereupon the basin 2D is passed laterally into straddling relation to the exterior portion of the mixer or agitating device shaft I4, and so positioned that the spout 2| is aligned with said opening or port 23, and the male coupler members 29 are aligned with the female coupler members 28 (see Fig. 3). When thus positioned the basin 20 is thrust down onto the top of the cover member Il so that its spout 2I enters through the opening or port 23 into communication with the mixing vessel interior, and so that the male coupler members 29 enter into and so as to be gripped by the female coupler members 28 (see Fig. 2). It will be Associated with said opening or port 23V apparent that, when the basin is thus mounted, it will be securely held against displacement or upset, and so that its content is guarded against spillage during use thereof in connection with mixing manipulation of the utensil.

When the basin 20 is mounted for .use in the manner above described, the ingredient to be added to a preliminary mixture already contained in the mixing vessel III is deposited in said basin, wherefrom it will gradually flow or drip through the discharge spout 2l into the content of said mixing vessel I0 while the mixer or agitating device is being manipulated by the operator, and consequently the added ingredient thus introduced will be so delivered as to assure desired emulsication thereof or blending thereof with the initial mixture.

When the mixing Vessel is desired to be used I for ordinary mixing operations, requiring no subsequent introduction of an added ingredient, the basin 2U may be removed and laid aside, and the cover disc 24 positioned to close the opening or port 23 against outward spatter of the composition operated upon under such circumstances.

Having now described my invention, I claim:

1. In combination with a cover member of a mixing vessel, an auxiliary ingredient feeding means adapted to be detachably mounted on said cover member, said cover member having a port, a manipulatable closure for said port, said feeding means comprising a basin having a discharge spout dependent from its bottom adapted to be inserted through said port for communication with the mixing vessel interior, and means for releasably coupling said basin in secured assembled relation to the cover member.
